Internet Draft - draft-ietf-isis-wg-mib-26.txt December 2005
Abstract
This document describes a management information base for the IS-IS
Routing protocol when it is used to construct routing tables for IP
networks.
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
This memo is based on an IETF draft by Chris Gunner. This version
has been modified to include MIB-II syntax, to exclude portions of
the protocol that are not relevant to IP, such as the ES-IS protocol,
and to add management support for current practice.

1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580]

2. Overview
This document describes a management information base for the IS-IS
Routing protocol as described in ISO 10589 [ISO10589], when it is
used to construct routing tables for IP networks, as described in RFC
1195 [RFC1195]. The objects are mainly derived from the GDMO
definitions in ISO 10589 and from the GDMO definitions in ISO 10733
[ISO10733]. There are also additional objects to manage the IP-
specific functionality of Integrated IS-IS operation.
This MIB imports definitions from SNMPv2-TC [RFC2579], SNMPv2-SMI
[RFC2578] SNMPv2-CONF [RFC2580], SNMP-FRAMEWORK-MIB [RFC3411],
DIFFSERV-MIB [RFC3289], IF-MIB [RFC2863], and INET-ADDRESS-MIB
[RFC4001]. See the imports section of the MIB for the specific items
imported.
This MIB defines some objects to manage Mesh Groups, described in
[RFC2973] and a three-way handshake for point-to-point adjacencies
described in [RFC3373].
The IS-IS MIB defines the following objects:
System-wide Attributes
- isisSystem
This table contains information specific to a single instance of
the IS-IS protocol running on a router.
- isisManAreaAddr
This table includes area addresses manually configured which are
used to control the associations formed between Level 1
Intermediate Systems.
- isisAreaAddr
This table includes area addresses reported in relevant L1 LSPs.
- isisSummAddr
This table holds summary addresses configured for each Level 2
instance of the IS-IS protocol running on a router.
- isisRedistributeAddr
This table provides criteria to decide if a route should be

Internet Draft - draft-ietf-isis-wg-mib-26.txt December 2005
leaked from L2 to L1 when Domain Wide Prefix leaking is enabled.
- isisRouter
This table holds the hostname and router ID for Intermediate
Systems in the network.
- isisSysLevel
This table contains information specific to a domain (Level 2) or
an area (Level 1) of the IS-IS protocol.
- isisNextCircIndex
This scalar is used to provide a unique circuit index.
Circuit-specific Attributes
- isisCirc
This table contains information specific to a point-to-point or a
broadcast interface in the system.
- isisCircLevel
This table contains information specific to a one Level 1 or
Level 2 of an interface.
Counters
- isisSystemCounter
Counters in the System table, such as times we have wraped a
sequence counter on one of our Link State PDUs.
- isisCircuitCounter
Counters of events particular to a circuit, such as PDUs with an
illegal value of the System ID field length.
- isisPacketCounter
Expires June 2006 [Page 4]
Internet Draft - draft-ietf-isis-wg-mib-26.txt December 2005
Counts of ISIS Protocol PDUs broken down into packet type.
Attributes associated with an Adjacency
- isisISAdj
This table contains information about adjacencies to routers
maintained by the protocol. Entries in this table cannot be
created by management action: they are established through the
Hello protocol.
- isisISAdjAreaAddr
This table contains the set of Area Addresses of neighboring
Intermediate Systems as reported in IIH PDUs.
- isisISAdjIPAddr
This table contains the set of IP Addresses of neighboring
Intermediate Systems as reported in received IIH PDUs.
- isisISAdjProtSupp
This table contains the set of protocols supported by neighboring
Intermediate Systems as reported in received IIH PDUs.
Attributes associated with addresses
- isisRA
The Reachable Address Table.
This table contains information about an address prefix manually
configured on the system or learned through another protocol.
- isisIPRA
The IP Reachable Address Table.
This table contains information about IP reachable address
manually configured on this system or learned from another
protocol.
Expires June 2006 [Page 5]
Internet Draft - draft-ietf-isis-wg-mib-26.txt December 2005
Attributes associated with Link State PDU Table
- isisLSPSummaryTable
The Link State PDU Summary Table
This table contains information contained in the headers of Link
State PDUs stored by the system.
- isisLSPTLVTable
The Link State PDU TLV Table
This table holds the sequence of TLVs that make up an LSP
fragment.
Attributes associated with a Notification
- isisNotification
This table defines attributes that will be included when
reporting IS-IS notifications.

DESCRIPTION
"The type of mapping to be employed to ascertain the SNPA
Address which should be used in forwarding PDUs for this
Reachable Address prefix. This object follows the
ManualOrAutomatic behavior. The following values of
mapping type are defined:
none: The mapping is null because the neighbor SNPA is
implicit by nature of the subnetwork (e.g. a
point-to-point linkage).
explicit: The subnetwork addresses in the object
isisRASNPAAddress is to be used.
extractIDI: The SNPA is embedded in the IDI of
the destination NSAP Address. The mapping
algorithm extracts the SNPA to be used
according to the format and encoding rules of
ISO8473/Add2. This SNPA extraction algorithm can
be used in conjunction with Reachable Address
prefixes from the X.121, F.69, E.163 and E.164
addressing subdomains.
extractDSP: All, or a suffix, of the SNPA is embedded
in the DSP of the destination address. This SNPA
extraction algorithm extracts the embedded
subnetwork addressing information by performing a

Internet Draft - draft-ietf-isis-wg-mib-26.txt December 2005
logical AND of the isisRASNPAMask object value
with the destination address. The part of the
SNPA extracted from the destination NSAP is
appended to the isisRASNPAPrefix object value to
form the next hop subnetwork addressing
information."
